  • A relationship between wave dispersion and fracture strength for a composite material

    Creator:
    Ilcewicz, Larry Bert
    Abstract:
    Wave dispersion and fracture are phenomena that involve. mechanisms triggered at the scale of a material's internal structure. Experiments were performed with a candidate material to judge the hypothesis that wave dispersion measurements can be used to nondestructively predict fracture strength. Wood-based particleboard was chosen as the candidate material because...

  • An empirical study on the process of mechanical design

    Creator:
    Stauffer, Larry A.
    Abstract:
    An information processing model of the problem-solving performance of mechanical designers is presented for four design tasks: conceptual assembly design, layout component design, detail component design, and catalog selection. These tasks are organized into six kinds of segments called episodes, which describe the goal structure of the designer while performing...

  • Optimization of staged rankine energy conversion cycles for high efficiency

    Creator:
    Simmons, Larry Dean
    Abstract:
    Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...

  • Particulate and total gaseous hydrocarbon emissions from a gas heated veneer dryer

    Creator:
    Shigehara, Roger T.
    Abstract:
    A source test was conducted to determine the particulate and the total gaseous hydrocarbon emissions from a gas heated veneer dryer. Samples were taken on eight separate days from the exhaust stacks while the dryer was processing Douglas fir veneer. Of the eight days, three was used to determine the...

  • Characterization of expert solutions to inform instruction and assessment in an industrially situated process development task

    Creator:
    Sherrett, Ben U.
    Abstract:
    What constitutes a quality solution to an authentic task from industry? This study seeks to address this question through the examination of two expert solutions to an authentic engineering task used in the Chemical, Biological and Environmental Engineering curriculum at Oregon State University. The two solutions were generated by two...

  • Hybrid Desktop Processes for Integrated Deposition and Low-cost, In-situ Sintering of Metallic and Non-metallic Conductive Nanoparticles

    Creator:
    Bhandari, Roshan
    Abstract:
    Microscale continuous thin films or patterned conductive structures find applications in thin film electronics, energy generation and functional sensor systems. An emerging alternative to conventional vacuum based deposition of such structures is the additive deposition and sintering of conductive nanoparticles, to enable low temperature, low- cost and low energy fabrication....

  • The effects of various pre-weighing procedures on the reported weights of air pollutants collected by filtration

    Creator:
    Kowalczyk, John F.
    Abstract:
    A study was conducted to determine what effects the type of pollutants, storage conditions, storage time, and method of sample conditioning have on the reported weight of an air pollutant collected by filtration. Samples were collected from a refuse dump, an arc furnace smelting nickel ore, and a rotary kiln...

  • Effect of hydrous ethanol on crankcase oil dilution

    Creator:
    Khalifa, Gamaleldin A.
    Abstract:
    Adequate lubrication is of the utmost importance in internal combustion engines. Low temperature operation with low-proof alcohol may create some operational problems if alcohol and or water accumulates in the crankcase oil. Condensates of unburned alcohol and water may be blown into the crankcase oil with blow by gases. The...

  • Orb Web Vibrations: Modeling, Localization, and Measurement

    Creator:
    Otto, Andrew W.
    Abstract:
    The orb web is a multipurpose structure---serving as a home for its inhabitant spider, as a prey capture device, and as a physical extension of the spider’s sensing abilities. Biologists are particularly interested in the spider’s ability to locate prey trapped in its web by sensing the vibrations induced from...

  • Transient fuel pin temperature calculations using describing functions

    Creator:
    Guidotti, Timothy E.
    Abstract:
    An important element in rector safety and fuel performance assessments is the efficient calculation of the time dependent temperature profiles within reactor fuel pins. Because the fuel pins have temperature dependent thermal properties, the governing partial differential equations are nonlinear. Traditionally, finite difference or finite element methods have been used...
